In WarriorJS, you write JavaScript or TypeScript to guide a warrior through towers full of enemies. Each floor is a puzzle: battle sludge, dodge archers, rescue captives, and reach the stairs alive. The code you write is the strategy — there's no clicking, no dragging, just logic and sharp thinking.
Whether you're writing your first if statement or refactoring for a perfect
score, every floor will test you.
